config ACPI_WMI
tristate "WMI"
depends on ACPI
help
This driver adds support for the ACPI-WMI (Windows Management
Instrumentation) mapper device (PNP0C14) found on some systems.
ACPI-WMI is a proprietary extension to ACPI to expose parts of the
ACPI firmware to userspace - this is done through various vendor
defined methods and data blocks in a PNP0C14 device, which are then
made available for userspace to call.
The implementation of this in Linux currently only exposes this to
other kernel space drivers.
This driver is a required dependency to build the firmware specific
drivers needed on many machines, including Acer and HP laptops.
It is safe to enable this driver even if your DSDT doesn't define
any ACPI-WMI devices.

For more information about this driver see
<file:Documentation/admin-guide/laptops/thinkpad-acpi.rst> and

This driver was formerly known as ibm-acpi.
Extra functionality will be available if the rfkill (CONFIG_RFKILL)
and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
Note that if you want ThinkPad-ACPI to be built-in instead of
modular, ALSA and rfkill will also have to be built-in.

config THINKPAD_ACPI_ALSA_SUPPORT

help
Enables monitoring of the built-in console audio output control
(headphone and speakers), which is operated by the mute and (in
some ThinkPad models) volume hotkeys.
If this option is enabled, ThinkPad-ACPI will export an ALSA card
with a single read-only mixer control, which should be used for
on-screen-display feedback purposes by the Desktop Environment.
Optionally, the driver will also allow software control (the
ALSA mixer will be made read-write). Please refer to the driver
documentation for details.
All IBM models have both volume and mute control. Newer Lenovo

config THINKPAD_ACPI_UNSAFE_LEDS
bool "Allow control of important LEDs (unsafe)"
depends on THINKPAD_ACPI
help
Overriding LED state on ThinkPads can mask important
firmware alerts (like critical battery condition), or misled
the user into damaging the hardware (undocking or ejecting
the bay while buses are still active), etc.
LED control on the ThinkPad is write-only (with very few
exceptions on very ancient models), which makes it
impossible to know beforehand if important information will
be lost when one changes LED state.
Users that know what they are doing can enable this option
and the driver will allow control of every LED, including
the ones on the dock stations.
Never enable this option on a distribution kernel.
Say N here, unless you are building a kernel for your own
use, and need to control the important firmware LEDs.

Allows the thinkpad_acpi driver to provide an interface to control

display state, video output devices in use, whether there is a X
server running, phase of the moon, and the current mood of
Schroedinger's cat. If you can use X.org's RandR to control
your ThinkPad's video output ports instead of this feature,
don't think twice: do it and say N here to save memory and avoid
bad interactions with X.org.
NOTE: access to this feature is limited to processes with the
CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms
where it interacts badly with X.org.
If you are not sure, say Y here but do try to check if you could
be using X.org RandR instead.
config THINKPAD_ACPI_HOTKEY_POLL
bool "Support NVRAM polling for hot keys"
depends on THINKPAD_ACPI
default y
help
Some thinkpad models benefit from NVRAM polling to detect a few of
the hot key press events. If you know your ThinkPad model does not
need to do NVRAM polling to support any of the hot keys you use,
unselecting this option will save about 1kB of memory.
ThinkPads T40 and newer, R52 and newer, and X31 and newer are
unlikely to need NVRAM polling in their latest BIOS versions.
NVRAM polling can detect at most the following keys: ThinkPad/Access
IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

help
This is a driver for System76 laptops running open firmware. It adds
support for Fn-Fx key combinations, keyboard backlight, and airplane mode
LEDs.
If you have a System76 laptop running open firmware, say Y or M here.

This driver adds support for hotkeys found on Topstar laptops.
If you have a Topstar laptop, say Y or M here.
config SERIAL_MULTI_INSTANTIATE
tristate "Serial bus multi instantiate pseudo device driver"
depends on I2C && SPI && ACPI
help
Some ACPI-based systems list multiple devices in a single ACPI
firmware-node. This driver will instantiate separate clients
for each device in the firmware-node.
To compile this driver as a module, choose M here: the module
will be called serial-multi-instantiate.
config MLX_PLATFORM
tristate "Mellanox Technologies platform support"
depends on I2C
select REGMAP
help
This option enables system support for the Mellanox Technologies
platform. The Mellanox systems provide data center networking
solutions based on Virtual Protocol Interconnect (VPI) technology
enable seamless connectivity to 56/100Gb/s InfiniBand or 10/40/56GbE
connection.
If you have a Mellanox system, say Y or M here.
config TOUCHSCREEN_DMI
bool "DMI based touchscreen configuration info"
depends on ACPI && DMI && I2C=y && TOUCHSCREEN_SILEAD
select EFI_EMBEDDED_FIRMWARE if EFI
help
Certain ACPI based tablets with e.g. Silead or Chipone touchscreens
do not have enough data in ACPI tables for the touchscreen driver to
handle the touchscreen properly, as OEMs expect the data to be baked
into the tablet model specific version of the driver shipped with the
the OS-image for the device. This option supplies the missing info.
Enable this for x86 tablets with Silead or Chipone touchscreens.

config INTEL_IMR
bool "Intel Isolated Memory Region support"
depends on X86_INTEL_QUARK && IOSF_MBI
help
This option provides a means to manipulate Isolated Memory Regions.
IMRs are a set of registers that define read and write access masks
to prohibit certain system agents from accessing memory with 1 KiB
granularity.
IMRs make it possible to control read/write access to an address
by hardware agents inside the SoC. Read and write masks can be
defined for:
- eSRAM flush
- Dirty CPU snoop (write only)
- RMU access
- PCI Virtual Channel 0/Virtual Channel 1
- SMM mode
- Non SMM mode
Quark contains a set of eight IMR registers and makes use of those
registers during its bootup process.
If you are running on a Galileo/Quark say Y here.
config INTEL_IPS
tristate "Intel Intelligent Power Sharing"
depends on ACPI && PCI
help
Intel Calpella platforms support dynamic power sharing between the
CPU and GPU, maximizing performance in a given TDP. This driver,
along with the CPU frequency and i915 drivers, provides that
functionality. If in doubt, say Y here; it will only load on
supported platforms.
